  • Clinical characteristics of 96 hospitalized patients with coronavirus disease 2019

    ObjectiveTo analyze the clinical characteristics of coronavirus disease 2019 (COVID-19), identify the high-risk factors which promoted the disease progression into severe or critical cases, and provide clinical guidance.MethodsNinety-six cases of clinically diagnosed coronavirus disease 2019 were collected and analyzed from General Hospital of the Yangtse River Shipping from January 20 to February 14, 2020. According to clinical classification, those cases were divided into two groups: mild group, including common and mild cases, and severe group including severe and critical cases.ResultsThere were more than half of patients ages>60 years old and severe or critical illness (61.5%, 56.3%), and obese patients accounts for 45.8%, the complication of hypertension accounts for 52.1%. The average time from onset to hospitalization was (6.1±2.6) days, and the average hospitalization days were (15.7±6.3) days. Compared with the mild group, the number of male patients in the severe group was more (57.4% vs. 35.7%, P<0.05), the numbers of elderly patients were larger (77.8% vs. 40.5%, P<0.01), and more obese peoples (55.6% vs. 33.3%, P<0.05). Cough symptom was more common in clinical presentation in the severe group (81.5% vs. 61.9%, P< 0.05). Patients with the complication of hypertension or diabetes occupied a higher proportion in the severe group, which were 64.8% vs. 35.7% and 35.2% vs. 14.3% (P< 0.05), respectively. And the rate of hypoxemia in admission of the severe group was significantly higher (79.6% vs. 9.5%, P< 0.01).ConclusionsThe cases of ages>60 years old and severe or critical illness in coronavirus disease 2019 occupy a higher proportion, and the complication of hypertension accounts for high proportion. Men, ages>60 years old, obese, coughing symptoms, with hypertension and / or diabetes, hypoxemia upon admission are high risk factors for progression into severe and critical cases.

  • A case of hypersensitivity pneumonitis presenting as progressive fibrotic interstitial lung disease and literature review

    ObjectiveTo strengthen the understanding to hypersensitivity pneumonitis and make early diagnosis and standard treatment by analyzing the clinical features, the diagnosis and treatment of a patient diagnosed as hypersensitivity pneumonitis presenting as progressive fibrotic interstitial lung disease in combination with literature review.MethodsThe diagnosis and treatment process and relevant clinical data of the patient were analyzed retrospectively and literatures were reviewed. Based on 282 relevant literatures, the diagnostic methods, treatment and prognostic factors of hypersensitivity pneumonitis were summarized.ResultsThe patient, female, 45 years old, self-employed, was admitted to the hospital due to "cough, sputum for 9 years, dyspnea for more than 6 months" without obvious extrapulmonary clinical manifestations. Creaks at the bottom of the lungs and clubbed toes were found through physical examination. High-resolution computed tomography indicated that the main manifestations were ground glass and grid-like shadows, presenting characteristics of interstitial pneumonia. The pulmonary lesions aggravated gradually, and part of the lung lobe presented honeycomb lung at the time of diagnosis. Eight years ago, she performed fibrobronchoscopy in other hospital revealing an increased lymphocyte proportion (39%) in bronchoalveolar lavage fluid. Lung function suggested very severe restrictive ventilation dysfunction. She was given prednisone for a short time, and the drug was stopped by herself with uncertain efficacy. Later, she performed frozen lung biopsy suggesting peribronchiolar metaplasia interstitial broadening with lymphocytic infiltration, without granuloma or fibroblast lesions. No obvious abnormity was seen in makers of infections and immunology. At this point, the patient was clearly diagnosed as hypersensitivity pneumonitis. Meanwhile, the patient's pulmonary lesions were still mainly made of ground glass and plaques, partly with changes like honeycomb. Poor response was obtained with anti-inflammatory treatment of prednisone for 3 months and anti-fibrosis treatment of pirfenidon for more than 2 months. Literature review resulted in 87 patients, including 39 males (44.82%) and 48 females (55.18%), with an average age of (47.0±18.4) years. Seventy patients (80.46%) had clear allergens. 3.45% patients' lymphocyte percentage in bronchoalveolar lavage fluid ranged from 20% to 39%, and 19.54% patients' lymphocyte percentage was more than 40%. 4.60% of the patients achieved remission through detachment from allergens; 71.27% of the patients achieved remission with glucocorticoid treatment, 14.94% improved with glucocorticoid treatment, and 1.15% died; 6.89% of the patients achieved remission after receiving anti-allergy therapy. Patients with chronic hypersensitivity pneumonia were found with poor prognosis.ConclusionsIn patients with diffuse interstitial pulmonary fibrosis with unknown cause, transbronchoscope freezing lung biopsy as early as possible is a feasible method for early diagnosis and improving prognosis. Patients with hypersensitivity pneumonitis with a long course of pulmonary fibrosis have a poor response to glucocorticoid and other classic treatments, and most of them have a poor prognosis.
